大豆施肥是一个复杂的技术问题。施多了增加成本,甚至遭致减产,施少了满足不了高产对养分的需求。同时,施多或施少都不能与其他栽培措施相协调。大豆模式化施肥是针对经验施肥的弊病而提出的一种科学施肥方法。它的中心内容是根据前茬玉米亩产量来决定后茬大豆施肥量。
Soybean fertilization is a complex technical issue. Apply more to increase costs, and even suffered cutbacks, Shi less can not meet the high yield of nutrient demand. At the same time, facilities or facilities can not be coordinated with other cultivation measures. The modeled fertilization of soybean is a scientific fertilization method proposed for the shortcomings of experienced fertilization. Its central content is based on the yield of the former crop of corn to determine the amount of soybean fertilizer after the crop.
